Elastic Field Series – Part I: The Fundamental Postulates of the Unified Elastic Field

This opening paper of the Elastic Field Series introduces the Unified Elastic Field Model — a framework in which the entire Universe is described as a single continuous medium capable of oscillation and tension. All observable phenomena — matter, motion, gravitation, light, and energy — are manifestations of the same underlying elastic field, structured by standing and traveling waves. The paper formulates the five fundamental postulates that define the nature of this field, the role of energy as wave tension, and the principle that every point of space carries the potential to store and transmit information. These foundations establish the conceptual and mathematical base for all subsequent parts of the series.
